How to set static DNS servers in debian 9?

Question

linux

Hello!
How to use "your" DNS servers, and not those that are installed via DHCP? In other words, how to hard-fix the DNS servers used so that they do not change every time the system is rebooted?
If you make a script that overwrites /etc/resolv.conf, will that be enough? Or manually configure /etc/network/interfaces? Are there other more suitable solutions?
Or is it configured somewhere in the NetworkManager settings? If yes, where and how?
Thanks in advance.
